I would consult with your physical therapist and orthopedist as healing time frame are dependant on a number of factors:
Previous activity level
Extent of damage
Quality of repair
Quality of bone (seen during scope)
Also, we look at progression of range of motion, strength and functional activities (walking, squatting etc)
Eight weeks is still fairly early for this type of repair with grade 5 degeneration.
